This image from Reddit builds the case that a tank design for Command & Conquer Tiberium Alliances appears quite similar to a Games Workshop-designed tank from the Warhammer 40K series. Games Workshop is known for fiercely defending its intellectual property rights, so there is rampant speculation that if this claim turns out to be valid, legal action is likely to follow. Thanks Strategy Informer.

From what I call of the BGG furor, they were hosting a lot of files, which put together as a whole pretty much obviated the need for ever buying the game if you had a printer. GW sent a notice that BGG was in violation, without specifying what exactly was in violation of what, and in response BGG nuked everything. Fandom went apeshit, life went on.

I don't know anything about WHAlliance (a fansite for Warhammer Online, not 40K), but... well, they obviously weren't sued into oblivion and there are people posting today. The thread kind of trails off so I don't know how that ended, but I doubt they went the "millions of dollars on lawyers" route so probably they came to an agreement?

The army tool thing is pretty shitty, but GW has been selling army tools for a long while. I think they should have made them free years ago, but if they're not going to discontinue them then obviously they're going to crush their competitors.
